Lightscribe
Definition:
Lightscribe is an innovative way to add labels to your own CDs and DVDs. Instead of printing a label that sticks to the CD or DVD, Lightscribe etches your design directly on the media. This requires you to buy a Lightscribe disc drive for your computer, install the Lightscribe software, and use specially made Lightscribe CD and DVDs.
Here's a word you may not know...
DPI
DPI stands for dots per inch and is a common term used to describe the quality of a printer. If you can imagine that a printed character on a page is made up of many tiny dots, the more dots used to create that character, the better the resulting character will look. DPI describes how many of these dots can fit into one inch of a document. The higher the DPI the better the quality of the printed document.
